Submit a comment to the NYPA

In 2023 New York State passed the Build Public Renewables Act that authorized our only public utility, the New York Power Authority, to build renewable energy source where the private sector is falling short. NYPA has now published a draft of its plan, but it, too, falls far short of what we need. NYPA will take comments from the public until December 13. All you need to write a comment is in this comment prep. The sheer number of comments pushing them to do better is critical. Your comment doesn't need to be long or complex--every comment counts. So click Take Action and comment today!
